ZARPAX products help you take control of humidity in your home, boat or car. The dehumidifiers in the ZARPAX family combat moisture and musty odors in enclosed spaces with low ventilation. Our humidifiers increase humidity in rooms that are too dry due to airconditioning or central heating. Our products can help make your personal environment healthier.

Moisture is present in every home. Every day, litres of water are produced by the house’s residents (people and pets) through perspiration and exhalation. Activities such as cooking, washing, showering and bathing also create moisture through evaporation. The average household produces about 10 to 15 litres of water per day. Moreover, rising ground water can also form a significant source of moisture problems in your environment. So long as there is sufficient ventilation, moisture does not cause any problems; but it is those small, poorly ventilated spaces where problems arise. This is where ZARPAX really feels at home!

As ZARPAX dehumidifiers do not leak, they can be placed anywhere indoors. However, the products should be kept away from grease, oil and water (liquid form). You can use the attached string to hang a ZARPAX dehumidifier between your clothing.

Always place the product in or on a clean microwave-safe dish or plate. If you are not sure if your dish is microwave-safe, you can use tempered glass ovenware (Pyrex). To be on the safe side, you can place a double-folded kitchen paper under your ZARPAX. The indicator should always be facing upwards when recharging.

You must realize that the average household sometimes produces 10 to 15 liters of water vapor per day. No dehumidifier can absorb all of this moisture. This is also not necessary since the excess moisture will leave the home through ventilation. Dehumidifiers such as ZARPAX and other products are intended to absorb moisture in places where there is insufficient ventilation to remove it. Normally the amount of moisture in these small rooms (e.g. cellar cupboard, kitchen sink cupboard) is not very large in terms of the number of liters, but causes problems because the moisture cannot escape through ventilation. Yet the removal of the relatively small amount of moisture from the space can resolve the problem. With ZARPAX dehumidifiers, this absorbed moisture is then evaporated in a place where it can be more easily removed through ventilation (kitchen) – with other products it is poured down your drain with the corrosive residue of the hygroscopic salt.

A new ZARPAX bag can absorb about 40% of its content weight in water from the air. This has been verified by an independent laboratory. The maximum capacity itself will not decrease significantly after you start using it. However, when you recharge it at the recommended time and wattage some water will be retained inside the bag. This prevents the bag overheating in the microwave when the water has evaporated. We therefore strongly recommend not trying to remove every last droplet of water and sticking to the recommended recharging time. We usually compare it to the fuel reserve a car needs. It would not be safe to wait until the very moment the tank runs dry before refueling your vehicle. That is why some gasoline is always kept in reserve.

Not all silica beads are. But ZARPAX beads can be readily regenerated. While over time some of the beads might split due to the stress of steam escaping that has no significant effect on the performance. This has been independently verified.

ZARPAX can be recharged in the microwave oven, but the metal grate must always be removed due to heat development. If necessary, a double-folded kitchen paper can be placed under ZARPAX while recharging to retain excessive moisture. A suitable dish should always be placed under ZARPAX during regeneration.

No, unfortunately this is not possible without damaging the product. If you do not have a microwave oven available, you can recharge the bag in the sun or on a central heating radiator if necessary. This, however, will take much longer than in the microwave oven and does not offer optimal results due to the irregular heating.

As the indicator needs to react to small changes in the humidity level, it is very sensitive to liquid water. When ZARPAX is being recharged drops of water may form beneath ZARPAX. If the indicator were to face downward, these drops could damage the indicator function.

The indicator on your ZARPAX will show signs of wear and tear over time. This is normal. The product can still be used however. To see when ZARPAX is fully saturated and ready to be recharged, you can check the weight of your ZARPAX.

The indicator is very sensitive, because it needs to react to small variations in humidity. When the indicator comes into contact with liquid water by accident, the indicator might start to show stains. Therefore always recharge ZARPAX with the indicator facing upwards.

In a microwave oven that is not cleaned well, there can be a layer of grease at the bottom. In contrast to water, this grease does not evaporate and will become very hot in the microwave oven where it touches the bag. This can leave scorch marks on the bag and can even lead to damage of the bag. Prevent the fabric from touching grease and recharge ZARPAX in a clean dish and optionally use double-folded kitchen paper beneath the pouch.

In this case you are probably using your ZARPAX in a bathroom or similar space with fluctuating humidity levels. You can do this, but the strong fluctuations in the humidity level confuse the indicator. When the indicator keeps turning back to blue shortly after taking a bath or shower, the ventilation in the room itself is probably enough to take care of any excess moisture in the air. When ZARPAX is full of moisture, the product will no longer be able to remove any more moisture from the air. The indicator will change color depending on the current humidity level in the room. All you need to do is to regenerate it to restore its dehumidifying function.

After being used for a season, a camper/caravan can get really moist inside. The mattresses, pillows and similar items can literally contain many fluid ounces of moisture. It is recommended to remove such items from the camper/caravan before parking it for the off-season. Before locking it up it is also strongly recommended to give the camper/caravan time to air, so the largest part of moist can escape. After removing the mentioned items and proper ventilation, you can place 2 or more ZARPAX dehumidifiers inside. The same goes for boats) ZARPAX RV/Marine is ideally suited to the task.

After swallowing the contents of the product rinse the mouth and drink generous amounts of water. Swallowing the contents of ZARPAX reusable products (SiO2 pearls) is not likely to cause further negative health effects. The content is chemically stabile and not flammable. Consult your physician for further advise.

ZARPAX Reusable Deproducts do not leak and do not cause aggressive chemical reactions (such as corrosion). If the pouch containing the moisture-absorbing pearls breaks unexpectedly, the pearls will not harm your furniture or belongings. Please mind to keep the products away from children, as they are not toys and the contents can cause dehydration if swallowed.

ZARPAX Reusable and Single-Use products are chemically stabile and can usually be disposed as household waste at the end of their service life. ZARPAX i-Dry products are electrical devices and should usually be dropped off at designated recycling stations. Please dispose of ZARPAX products according to national and local regulation.
